Australian researchers have made an important breakthrough in understanding the composition of the tear film that protects our eyes, leading to more effective treatments for dry eye disease.

The project was a collaboration between researchers at UOW, QUT and the University of New South Wales. The results of the study are featured as the cover article in the August issue of the Journal of Lipid Research.

For more than 40 years, scientists have been trying to determine the precise composition of these lipids in order to understand how the tear film lipid layer works to prevent evaporation, while still providing a smooth surface to enable clear vision.
